Question

Sodium will react with chlorine to form sodium chloride (NaCl). Another cation, magnesium, will also react with chlorine to form magnesium chloride.

Answer 1

See explanation below

Step-by-step explanation:

Sodium will react with chlorine to form sodium chloride NaCl.

Na is a group I metal with 1 valance electron to become one Na+ ion to bond with one Cl- ion

Magnesium will also react with chlorine to form magnesium chloride MgCl2

Mg is a group II metal with 2 valence electrons become one Mg2+ ion to bond with two Cl- ions.

Both Na and Mg are metals while Cl is non-metals so the bond between metal and non-metal is ionic bond.

Hope this helps.
